Nadya [2.5K]

Answer:

The probability that the average score of the 49 golfers exceeded 62 is 0.3897

Step-by-step explanation:

The average score of all golfers for a particular course has a mean of 61 and a standard deviation of 3.5

$\mu = 61$

$\sigma = 3.5$

We are supposed to find he probability that the average score of the 49 golfers exceeded 62.

Formula : $Z=\frac{x-\mu}{\sigma}$

$Z=\frac{62-61}{3.5}$

$Z=0.285$

Refer the z table for p value

p value = 0.6103

P(x>62)=1-P(x<62)=1-0.6103=0.3897

Hence the probability that the average score of the 49 golfers exceeded 62 is 0.3897

The answer isn't A or B because those two are not factored. D is wrong because 8•8=64 not 16. So that leaves us with C (4•4=16).

If f^-1(x) is the inverse of f(x), which statement must be true?

k0ka [10]

F(f-1x) will be equal to x

take a simple example

f(x) = 2x

so x = f(x) / 2

f-1(x) = x/2

f(f-1x) = 2 ( x/2) = 2 * x/2 = x
